Fig. 24 is a detail sectional viewshowing more fully the adjustable connection between the gage K and plate N. Fig. 25 is asimilar view disclosing more fully the notched plate and its engaging projection, and Fig. 26 is also a detail View showing more fully the connect-ion between and relative position of gage K and plate N.

This invention relates to improvements in box-nailing machines; and it consists in the construction and novel combination-of parts, as hereinafter set forth.

Referring to the drawings, A designates the frame having its vertical front wall slotted centrally, as at B, and A is the hollow bed-frame.

C is a forwardly-projecting table having a downwardly-turued bearing-flange D at'its rear edge, which lies against the vertical front ot the frame. A transverse rib a, integral 6o with the flange I), projects through and moves in the slot B, and a plate l), screwedto said rib, has its edges projecting laterally beyond the slot-in the rear, and serves to steady the table.

The table is adj usted vertically by means of the screw E, which engages a threaded opening through the lug con the bed-frame, and has its upper end seated in the cup-bearing (l on the bottom of the table. A bevel-gear 7o e on the screw E meshes with a bevel-gearf on the horizontal shaft F, which is journaled in hangers depending from the table, andhas the operating-wheel G on its outer end.

H is the lower gage, extending across the face of the machine on the upper side of the table, and is to gage the work to the driven nails, its adj ustability (eitected as hereinafter described) permitting the sliding thereof to and from the work. Cheek-plates I on 8o each end of the gage H have a longitudinal rib g, adapted to slide in the grooves h, formed in the sides of the table, and the said gageis adjustable by means of the short lever Jon one side of the table. The said lever J is rigidly secured to one end of the transverse rod fi, which is journaled through the sides of the table, and has at the end opposite that engaged by the hand-lever a rigid collar j, provided with a projection 7c4 to engage the 9o notch 76X in the cheek-plate. A similar proj ection on the lever J engages a notch inthe l cheek-plate at the opposite side. 'By operating the lever J the gage may be moved. backward or forward and held as adjusted by pins passing through the cheek-plates and into' one of the series of openings in the side of the table.

K is the upper gage-bar, extending across the face of the frame near its upper end :oo

below the drivers, hereinafter described, to gage the work to the nails. The gage K is held in position by the integral bolts I, Fig. 14, which extend at right angles therefrom near each end through bearings in the hangers L, secured to the sides of the frame by bolts. The bolts l at their outer ends are provided with a wide bearing-head m, which moves in a slot opening through the rear depending arm of the hangers L, and a coiled spring n surrounds the slot between the head and the front arm of the hanger. Said springs are designed to return the gage when released by the operating-cams. Thumb-screws M, passing through threaded openings in the front arm of the hangers L, are designed to limit or regulate the rearward movement of the gage.

- Toincrease the bearing-width of the gage K, the plate N is provided at its lower edge and is adj ustably connected thereto by the screws t.

O,Fig. 12, is a transverse shaft having` bearings in the boxes p,which extend rearwardly from the frame, and a thumb-screw q is provided, in connection with one of said boxes, which acts after thefashion of a brake upon said shaft in order to regulate its movement. The shaft 0 is operated to give a fractional revolution thereto by means of the link Q, Figs. l and 2, pivoted at its lower end to the cross head R, adjustably connected by a screw-bolt to the vertical shaft S, which is reciprocated by the gear w on the main drivingshaft XV through the pitman c. The upper end of the link Q is pivoted to the bracket r on the shaft O, (see Fig. 12,) which carries the pivoted dog s, engaging with the ratchet t, secured on the said shaft O.

T represents step-cams on the shaft O, ad j ustable by rib-and-slot connection for operating the gage-plate K by striking against the bearing-heads m at every revolution of the shaft. The adjustability of the gage K is, as above intimated, to regulate the bearing-width of said gage upon the work or box, and that of the step T is to bring any one of its steps in position to act upon the heads.

U is a step-cam, also adj ustably secured by rib-and-slot connection to the shaft O near its center, designed to force the gages V,Fig. 9, throughv the openings in the face plate by engaging against the roller u, journaled in the frame of the gages V. The purpose of the gages V is to regulate the thickness of the boards of the boxes, as vwill more fully appear farther on. A coiled spring c on the bolt w, extending from the gage-frame through an opening in the frame V, serves to return the gagesfwhen released by the cam, and a setbolt (see Fig. l) is provided to regulate the return movement of the gages.

The cams above referred to are provided with steps or lifts, so that they may be regulated to project the gages, as desired, for the thickness of the boards of a box. l

A is a cross-bar journaled through th arms a', and having the arm B connecting with the vert-ically-reciprocating cam-plates C', which have bearings in the trame, and are designed to operate the two picker-bars D D, Fig. 4. One of said cam-plates C is provided with a double cam-face b', so that the bar D is operated at each movement of the cam, and the other cam-plate is provided with a single face c', so that its picker D is operated only at the downstroke, whereby an alternatin g action of the picker-bars is secured, effecting a successive feeding action of the nails from the box. `The said cam-plates are operated from the driving-gear by means of the arm E', which is rigidly connected at one end to the bar A and pivotally connected at its other end to the rod F which has a pivotal connection with the driving-gear F and oscillates the feed-box G. The feed-box G is pivotally connected to the frame at its upper end by arms G2 G2, projecting from the frame and receiving studs or pivots G3 G3 on the box, in order to permit of its vibration to shift the position of and direct the nails into the feeding-slots in the bottom of the box, and is divided into trays or stalls H and between adjacent trays the box G is provided with slot-openings CZ', through which the nails project and are fed to the pickers. The slots d near the lower end have the offset or shoulder e', Fig. 4, designed to retain or hold a series of nails in the slots when the'box is at its extreme downward pitch. The front I of the box is hinged by pintles or projections 'ix fix, projecting from the ends of the front I and entering the ends of the apertures (not shown) in the lower front edges of the box to actuate the fingers of said front, as presently described. The front I is provided with inwardly-projecting fingers f', which normally lie upon the lower end of each slot, and at the extreme downward pitch of the boxj a laterally-projecting lug g', Figs. 3 and 4, on the front l strikes against the trip h', Fig. l, and by turning the front on its pivots raises the fingersf from the slots, allowing the release of any nails that may become clogged in or rest crosswise over the slots. A spring s, as shown, returns the hinged front to -a closed position on the upward motion of the tray.

An inclined front plate J has slot-openings il', which register at their upper ends with the slots d', and provide a continuous way for the nails to the pickers K.

The nail-pickers K', Figs. 2t and 5, Awhich 'are for feeding the nails tothe chutes A2, are

j ournaled on the bolts j', upstandin g from the rigid portion of the front plate, and the rigid jaw k of each picker is preferably removable and made of hardened steel. The jaw l is provided with a threaded bolt m', which projects through an opening in the picker-head, as shown, and has an adj listing-nut n 011 its threaded end, and a coiled spring on said `bolt m allows the jaw to give slightly when picking the nail.

The picker-head and iixed jaw have a IOO IIO

ISO

curved form, so as to move in the concave notches L in the inclined plate when operated by the cams O', and the picker-bars D D actuated by the arm B of the bar A. A thumb-screw o' is adjustable in the slot p in the extension of the picker-head and engages the internally-threaded lug q', so as to shift the latter into engagement with the lugs r or 7", to thus permit of the actuation of either of the picker-bars. A coiled spring, secured to the frame and picker, returns the picker when released by the picker-bars.

As the nail is picked, itis dropped through the funnel-mouthed chute A2 into the chucks B2, which are adjustably secured by means of the thumb-screws C2, which pass through a slot in the transverse bar D2, Fig. 3,seeured at its ends to the blocks E2, which are vertically adjustable in the guideways F.

The chucks B2, Figs. 20 and 22, to hold the nails while being driven, consist of the clutcharms a2, pivoted near their upper ends within the recess h2, and having their adjacent sides at the lower portion grooved or concaved in cross-section, as at c2, through which grooves the drivers G2 force the nail, pressing the arms a2 outward on their pivots against the springs (l2, which return the arms to a closed position when the driver is Withdrawn. Spring-controlled and grooved pivoted levers e2 bear against opposite sides of the driver, and serve to guide it into the grooves c2.`

One side of the chuck-casing is removably secured by screws and has a hinged portion J' 5 f2, which is held in a closed position by the pivoted keeper g2. This hinged portion is provided so that the chute, which has its end projecting into the chuck, may be easily removed should a nail become clogged therein. luides e', adjustable to readily accommodate them to the size of the funnel-mouths of the chutes A2, and arranged above said funnelmouths of the chutes, are provided and are designed to prevent short nails from' turning over in their fall into said chute.

The guides e are rendered adjustable by thumb-bolts connected thereto and passed through slots z3 in the pendent portions of the front plate.

The drivers G2 have the head h2, and are laterally adjustable in the slot t2, formed in the cross-head H2 by the plate j?, (see Fig. 3,) which is rendered removable by securing thumb-screws, so that the drivers may be removed or new ones inserted. The cross-head H2 moves vertically in the guideways F and reciprocates with the cross-head R, being connected thereto by the vertical rods 12.

J2 is a supplemental nail-box, Fig. l, pivoted between thc standards K2, bolted to the frame. The said box J 2 is pivoted so that its rear side wall projects over the nail-tray for convenience in dumping nails therein, as required. To prevent the box from tipping accidentally, a suitable catch may be provided or a hook used, as shown.

It will be observed that the machine is operated from the band-wheel LX, the crank L', and gearingw F at the base of the machine. The band-Wheel is provided with a clutch mechanism, indicated at Z, as Figs. 16 and 17 in the drawings, which consists of a horizontal pawl Z', which engages a tooth Z on a disk-shaped closure Z secured to the shaft W, and which pawl is held in engagement with said disk-tooth Z by a spring Z. A hand-lever Z5 is adapted to engage with and permit the retraction of the pawl Z from the tooth Z of the disk-shaped closure Z when it is desired to disengage the clutch from the driving or band pulley shaft. The disk Z incloses or contains a series of alternating `balls Z6 and concave-faced blocks Z7, bearing upon an irregular-faced supplemental disk or cam ZS, secured to shaft NV. In this diskshaped closure is also a helical spring Z9, the tension of which holds the said closure in proper position upon the disk ZS. 1 j

It will be seen that by the actuation of the treadle X', so as to depress the lever X, the lever Z5 will be moved downward, and thus disengage the pawl Z from the tooth Z of the disk Z, fast to the driving-shaft- W', permitting the transmission of the motion of the band-wheel LX to said disk,in turn putting the said shaft in motion, as desired, to operate the machine. On the other hand, by removing pressure from said treadle the pawl will be again brought into engagement with the tooth ofthe said disk by the action of the spring Z4, and thus, though the bandwheel is still in motion, yet the shaft will be motionless, the friction al clutch just described permitting the band-wheel to rotate independentlv thereof, though in contact Wil h said disk. If desired, instead of actuating the treadle, the hand-lever Z5 may be operated directly to effect the disengagement of the pawl Z from the tooth Z of the disk Z of the driving-shaft XV', the lever being automatically returned to its original position when released by the action of the spring Z.

The operation is as follows: The pieces to form the box are temporarily put together and positioned upon the table c, the gages V and K determining that position, and the hopper or box G having the nails is given the required jarring movement to feed the nails therefrom upon. the inclined plate J', the hinged nail-conducting front I of the box G being raised so as to lift its lingers to permit the passage of the nails in event of clogging from the latter upon said plate J bythe action of the lu g g and the trip 7L. The nails passing out upon the plate J g are fed successively, one after the other, in the requisite number of rows two at an operation in the slots t' to the pickers K. The pickers two) being actuated by one of the cam-plates C', actuated by either one or the otherot' the bars DD, conduct the nails to the chutes A2, from which they are Wpassed or fed into the chucks B2, which, by means of the arms a2, hold the nails in position to be driven into the box by means ICO IIO

of the drivers G2 the cross-head H carrying which being actuated by the reciprocating cross-head R. After the nailing ot' one edge or end of the box to the ends or edges of the connecting-pieces, the work is then so disposedA as to present another end or edge upward to undergo a like nailing operation, the piece to be secured being' put in position thereon, and the required pickers K brought into requisition in the manner already pointed out, the aforesaid operation being continued until the nailing of the box is completed.
